SNMP is an Internet-standard protocol for collecting and organizing information about managed devices on IP networks.
It exposes management data in the form of variables on the managed systems organized in a MIB which describes the system status. These variables can then be remotely queried by managing applications.
Three significant versions of SNMP have been developed and deployed. SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security.
6WINDGate supports SNMPv1, SNMPv2c (basic authentication with community strings) and SNMPv3 (authentication with SNMP users).
